The City of Vacaville’s water system meets or exceeds state water quality standards and is a reliable drinking water supply and meets all state and federal water quality regulations prior to being provided to water customers.
Water quality standards are established by the U.S. Environmental Protection Agency (US EPA) and the California State Water Resources Control Board. The City extensively tests its water wells, treatment plants, and throughout the distribution system to verify water quality and ensure the water served to customers meets drinking water standards.
All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk.
